So far it hasn't been as bad as some of the reviews led me to believe. The only really bad part so far has been getting the jet intake to fit.
I finished filling, sanding and polishing the fuselage joints tonight so all that remains of the fuselage is filling around that bad fitting intake, but I'm too tired to tackle that tonight. Next will be the wings and they don't look like they will be too bad, but I'm sure they will require some filler around the fuselage joint.
